iii iuiiiiiiiiu iii Parkdale Project 999 • Reclamation Permit Exhibit I -Soils Information 1.0 Existing Information Based on the soil survey completed for the Fremont County Area by the Natural Resources Conservation Service (SCS 1995), the permit area is overlain by nine soil map units. These include the Kim loam, cool, 3 to 8 percent slopes (Map Unit 50); Louviers- Travessilla complex, 20 to 50 percent slopes (Map Unit 64); Nunn clay loam, 0 to 2 percent slopes (Map Unit 78); Otero fine sandy loam, 3 to 8 percent slopes( Map Unit 81); Riverwash (Map Unit 92); Roygorge very gravelly sandy clay loam, 25 to 50 percent slopes (Map Unit 98); Sedillo cobbly sandy loam, 4 to 25 percent slopes (Map Unit 100); Shanta loam, 0 to 3 percent slopes (Map Unit 104), and; the Ustic Torriorthents, bouldery -Rock outcrop complex, 35 to 90 percent slopes (Map Unit 120) map units. The following discussion summarizes the information developed for these units by the Natural Resources Conservation Service. 1.1 Kim loam, cool, 3 to 8 percent slopes This map unit consists of well drained soils forming in alluvium and eolian parent materials on fans and fan terraces. This map unit would be disturbed by the proposed gravel pit, facilities area, and recycling pond. The Kim soil, making up about 95 percent of the unit, is characterized by loam textures, strong effervescence, and moderate alkalinity to a depth of 60 inches. The coarse fragment content less than 5 percent throughout the profile. The effective rooting depth is 60 inches or more. This soil is non-saline and non-sodic. The hazazd of water erosion is moderate to very high. 1.2 Louviers-Travessilla complex, 20 to 50 percent slopes Occurring on hills, and canyonsides, this unit consists of shallow, well drained soils. It is scheduled for disturbance by the sandstone and granite mining operations. The Louviers soil is forming in residuum from shale and siltstone and covers approximately 40 percent of the unit. This soil is characterized by very channery clay loamy over clays to a depth of 16 inches. It is neutral to mildly alkaline, non-effervescent, non-saline, and non-sodic. The effective rooting depth is 10 to 20 inches. The Travessilla soil is forming in residuum primarily from sandstone and comprises approximately 35 percent of this unit. This soil is typically channery sandy loamy and sandy loamy to hard sandstone bedrock at 9 inches. It is non- to strongly effervescent, mildly alkaline, nonsaline, and nonsodic. The effective rooting depth is 4 to 20 inches. The hazard of water erosion is very high. 1.3 Otero fine sandy loam, 3 to 8 percent slopes This map unit consists of well drained soils forming in alluvium and eolian parent materials nn sideslopes and fans. This map unit is not proposed to be disturbed. The Kim soil, making up about 95 percent of the unit, is chazacterized by loamy Fine sand and
